YETI Daytrip 3L Snack Box
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes plastic, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What YETI Daytrip 3L Snack Box is made of, ingredients and materials
The Daytrip 3L is injection-molded plastic, most likely polypropylene (PP) or a PP-blend based on typical Yeti construction for rigid food containers. PP is a stable, food-contact plastic with no inherent BPA, and it does not leach significantly at ambient or cool temperatures. No coating, laminate, or chemical treatment is described by Yeti for this model, so concerns around ceramic glaze contamination or Teflon-type coating fumes do not apply.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Microplastics
If the container is repeatedly microwaved or exposed to hot liquids above 60C (140F), PP can soften, crack, or shed particles over years of use. Risk is low for intended cold/snack storage but rises with misuse.
Source, EPA ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
PP formulations used in food-contact containers are not formulated with BPA or BPS. No recalls or public health warnings link the Daytrip to bisphenol contamination.
Source, FDA ↗Phthalate plasticizers
Rigid polypropylene does not require phthalate plasticizers for flexibility. This product design does not involve soft PVC, vinyl, or flexible coatings where phthalates would be expected.
Heavy metals
Yeti's manufacturing standards and lack of public safety incidents suggest colorants and UV stabilizers meet FDA food-contact limits. No independent testing or brand disclosure is available to rule out trace elements entirely.
Source, FDA ↗Coating degradation and leaching from seams or closures
The Daytrip has no described coating or lamination. Plastic-to-plastic seams are inherent and stable at food-storage temperatures; no adhesives or sealant coatings are documented.
The full breakdown
The brand's record and disclosure
Yeti does not publish a formal PFAS policy or transparency report, and makes no public statement about intentional PFAS use in this product. The brand has a strong reputation for durable, food-safe hardgoods and has not faced recalls or public safety complaints for leaching hazards in lunch containers. However, the silence on PFAS manufacturing or intentional additives is typical of many consumer brands and does not confirm absence.
How it compares in its category
The Daytrip sits at the premium end of rigid plastic snack boxes. Most competitors in the category (Rubbermaid, Sistema, OXO) use similar PP formulations without coatings or additives. Unlike insulated lunch boxes with metal or fabric linings, this unlined design avoids potential off-gassing from foam or adhesives. Its simplicity and lack of compartment seals or gaskets reduces the number of potential leaching points.
If you buy it
Keep the container out of intense heat and direct sunlight to preserve plastic integrity over time; do not microwave or fill with boiling liquids. Hand wash or use gentle machine cycles to avoid stress cracks that can expose new plastic surfaces. Inspect quarterly for visible degradation, cloudiness, or small cracks, and replace if the material becomes brittle. For cold snacks, ambient-temperature foods, and short-term storage (days to weeks), this container is appropriate.
